Product Overview

XCU® slow-release fertilizer provides gradual, steady nutritional uptake for up to 10 weeks of plant response. XCU® fertilizer has the highest nitrogen (N) content (43%) and lowest sulfur content (4%) of any polymer-coated sulfur-coated urea (PCSCU) on the market. The value is more area can be covered per application using less fertilizer, which is more efficient and economical. Also, with less N lock-off more of the applied N is taken up and utilized by turfgrass or plants in the expected time frame.

advanced dual-coating Technology

Less sulfur coating reduces N lock-off and delivers more N

Coating integrity is maintained during transport, blending, bagging and application

Outer layers consist of a thin coating of elemental sulfur and polymer wax, which work together to protect the inner polymer coating

Inner layer consists of a thin, cross-linked polymer film that encapsulates and protects the urea granule

How It Works

3. With previous-technology SCUs, this pressure cracked the coating, immediately releasing N (catastrophic release). The inner polymer coating of XCU® fertilizer results in a hybrid of diffusion-based release and catastrophic release, resulting in a more consistent release profile.

4. After N release, the sulfur eventually breaks down into the soil where it may be taken up by the plant.

Product benefits

XCU® slow-release fertilizer has been widely used by superintendents, LCOs, municipal turf managers and professional landscapers to economically and efficiently promote a plant response of health, growth and color for up to 10 weeks per application.

Options and flexibility

XCU® fertilizer is available in sizes to fit a number of fertilization programs.

Only a portion of the N applied as conventional fertilizer is taken up by plants, but enhanced efficiency fertilizers (EEFs) increase N uptake. Increasing the XCU® fertilizer content in blends results in more efficient N use; the more XCU® fertilizer used, the better your blends work.
